Linear Amplifier Powers EGSM WCDMA Networks
PNS? Anadigics, Inc. announces its AWT6281 HELP3 WCDMA linear power amplifier for use in advanced 3G handsets for EGSM (Band 8) UMTS wireless networks. This amplifier extends the operating time of 3G handsets and data cards which is critical for successful operation using high-speed packet access (HSPA) networks. It provides full compliance with HSDPA and HSUPA requirements, and it reduces average current consumption by 75% compared to competing devices. The PA provides optimally low quiescent currents of 7 mA without a DC/DC converter, and it eliminates the need for an external voltage regulator. The self-contained 4 x 4 x 1.1 mm surface mount package incorporates matching networks optimized for output power, efficiency and linearity. ANADIGICS, Inc. 35 Technology Dr. Warren, NJ, 07059
